week 5 = Swiping method of using android application

Assalammualaikum..

For this week i have set myself to redesign the application so then the application going to be more friendly user for the blind people and also i have change the use of power supply on my circuit .

Before this the system have been powered up by the use of USB that connected to the Arduino and i think i find the difficulty for them to reconnect then on the system again . So here the solution for the project for the short term which is use the rechargeable battery . The battery that i have been used is




 . As  we know that by having button to the android application make them wondering how to use the button on the application so i have been doing some research on other method to use the function in that apps instead on push on the button option .

After do some research on tutorial in the youtube i figure out that we can do some method of swiping
to make the use of this apps easier . For the first time i have been testing on the normal swiping method first without interfaced any function through it . So here is the coding for the swiping method in the Blinavigator .

from the figure above i am going to explain the working of this coding . Canvas is a feature that we can use to move around on the apps . So when we choose the canvas from the option given in MIT APP INVENTOR , choose when it flung ,it is because we are going to apply swiping method . 

first if is when we absolute get heading means once our finger touch the screen and move to somewhere it going to fix our initial location of finger . let say  the finger initial less than 45 degree means the finger ready from the left side and swipe to right . it will decide that the situation is it is swiping to right method . then it will print to the text box ''right'' .. the same concept applied to the swiping left . 

we move on to the swiping up method , as we can see that the absolute heading is in between 45 and 135 which means our finger that touching the screen is at the centre and going to move to the positive up so the apps going to decide that the finger is moving/swiping up. 

Here is the simple design in confirming the functionality of the idea .

After functionality of the swiping is confirmed we put the same kind of procedure to the application . But still we have to rearrange each of the page and what page is going to be used in our apps.

For the next task i am going to redesign the pages that going to be used in the application and apply the swiping method to it .
